Gree E5 fault code

Gree air conditioning

What the Gree E5 fault code means, from the manufacturer's own service literature, and the UK models it applies to.

What it means

Whole-unit overcurrent protection

Total input current exceeded the limit.

Safety: Safe isolation before disconnecting the compressor or testing the inverter board — capacitors hold charge.

E5 on these comes from each model's own manual, which may not match the meaning above — tap yours to read it.

Now the harder half: proving what caused it

E5 names a symptom, not a root cause. In the app, the same code opens a guided investigation: what to measure first, the expected values for your exact model, and an honest verdict — including “nothing in this machine is broken” when that's what the readings say.
